Title: Means for and method of testing and indicating the condition of filters
IPC: B01D35/14
Filed: 1927-12-08
Abstract: 313,179. Marks, E. C. R., (A. C. Spark Plug Co.). Dec. 8, 1927, Filters, testing.-For testing and indicating the degree, of obstruction in filters for fluids under pressure, such as oil filters for motor-cars, the pressure in the supply conduit is indicated by a gauge arranged, for example, on the instrument board of the car and also the back pressure at the filter, which is normally less than the supply pressure. As shown, the supply pipe 1 has a pressure branch 9 controlling a pointer 7 in a gauge 6<a>, and communicates by a restricted opening in a coupling 2 with the delivery pipe 3 to the filter 4. A back pressure pipe 10 from the pipe 3 controls a second pointer 8 in the gauge. The pointer 7 will normally show a higher reading than the pointer 8, but is overtaken by the latter as back pressure is built up in the pipe 10 by obstruction accumulating in the filter. In a modification, the pipes 9 and 10 are controlled by a three-way cock so that the supply pressure and the back pressure may be read in turn, or two separate gauges for the pipes 9 and 10 may be used.

Title: Method for producing melamine
Filed: 1953-12-03
Abstract: A process for producing melamine by polymerization of cyanamide and/or dicyandiamide at a temperature ranging between 200 DEG  C. and 300 DEG  C. comprises introducing an aqueous cyanamide and/or dicyandiamide solution, in the form of a dispersion whose particle size does not exceed 100 microns, into a gaseous atmosphere heated to a temperature of 200-300 DEG  C., whereby the water from the dispersion is converted to dry steam containing a finely dispersed solid residue which yields melamine either simultaneously under the reaction conditions employed or in a separate heating stage.  The starting solution is preferably a lye of cyanamide and/or dicyandiamide resulting from the treatment of commercial calcium cyanamide with water and carbon dioxide.  The dispersion may be achieved by any known means of spraying or atomization giving fine droplets.  The process may be carried out in a single reaction chamber into which are introduced simultaneously and continuously the dispersion and heating gases, laden if required with steam, to raise the temperature to between 200 DEG  and 300 DEG  C.  Alternatively, the process may be carried out in two chambers, the dispersing and drying stage taking place in the first chamber, which is maintained at a temperature between 100 DEG  and 200 DEG  C. by the heating gases, and the reaction stage taking place in the second chamber, into which are introduced continuously and simultaneously the dried dispersion from the first chamber and further heating gases to raise the temperature to between 200 DEG  and 300 DEG  C.  The heating gases may be provided by the combustion of methane.

Abstract: 985, 286. Radio-active materials. SAUNDERS-ROE & NUCLEAR ENTERPRISES Ltd. Sept. 2,1963 [Sept. 8, 1962], No. 34466/62. Drawings to Specification. Heading G6R. A Bremsstrahlung source comprises an intimate mixture of a radio-active isotope material and a target material bonded and encapsulated in a radiation-resistant material, e.g. epoxy resin, which may incorporate additional target material. The intimate mixture may be produced by causing the radio-active isotope material to precipitate from solution in a suspension of the target material, causing the target material to precipitate from solution in a suspension of the radio-active isotope material, or precipitating the radio-active isotope material and the target material from a mixture of their solutions. In an example, excess ammonium fluoride solution is mixed with a solution of promethium-147 chloride in 0. 5N hydrochloric acid and the mixture added to a quantity of zircon flour in a container. The zircon flour is stirred into suspension in the solutions and the suspension heated to 70‹C. to precipitate the promethium out of solution as promethium fluoride. The suspension is then tipped into a filter cup, the filtrate drained away, and the intimate mixture of promethium fluoride and zircon flour left on the filter pad washed with water,dried and soaked in a strong acetone solution of a radiation-resistant epoxy resin and a catalyst. The acetone is allowed to evaporate and the epoxy resin solidified and hardened by hot curing. The resultant solidified layer is covered with two other epoxy resin layers. If required,the filter pad and the solidified layer may be removed from the filter cup and transferred to another more suitable container before the additional layers are applied.
